Question 1

Two Alloys X and Y contain Brass and Aluminum in the ratio 8 : 9 and 1 : 6 respectively. In what ratio should they be mixed so as to have 25% brass?

Accepted Answer

Use the rule of allegation. Brass in X is 8/17, in Y is 1/7. Desired brass is 1/4. Apply allegation: (1/4 - 1/7) : (8/17 - 1/4) = 3/28 : 15/68. Simplify to 17:35.

Question 2

Find the missing number in the series1, 11, 99, 693, 3465, ?

Accepted Answer

The pattern is multiplication by consecutive prime numbers starting from 11. The series is 1 * 11 = 11, 11 * 9 = 99 (error in question, should be 11*9), 99 * 7 = 693, 693 * 5 = 3465. The next multiplier is 3. So, 3465 * 3 = 10395.

Question 11

In the third year, if A, B and C invested the same amount as before in the second of the year, what is C’s share in a profit of Rs. 60000?

Accepted Answer

The question implies that the investment ratio for A, B, and C remains constant as in the second year. Assuming the ratio is 2:3:5, C's share is (5/10) * 60000 = Rs. 30000. However, the provided correct answer is 24000, which suggests a different underlying ratio or context not fully provided in the snippet. If the ratio was 2:3:3, then C's share would be (3/8)*60000 = 22500. If the ratio was 2:3:4, then C's share would be (4/9)*60000 = 26666.67. Given the options, the question is incomplete without the actual investment ratio for A, B, and C.

Question 12

Who amongst the following likes Kolkata ?

Accepted Answer

To answer this, one must refer to the provided data (not included here). Assuming 'H' is directly stated as liking Kolkata in the data, it is the correct choice.

Question 13
